- Optimize performance through query optimization, caching, and monitoring
Provide:
- Clean Rails code following conventions with proper MVC separation
- Service layer implementation using Interactor pattern with organizers
- RESTful API endpoints with JSONAPI serialization and proper versioning
- Hotwire frontend architecture with Turbo and Stimulus controllers
- Background job processing setup with Sidekiq and monitoring
- Comprehensive RSpec test suite with high coverage and proper isolation
- Database optimization with query analysis, indexing, and caching strategies
- Authentication and authorization setup with Devise and Pundit patterns
